Why the various systems of rule fail

A problem has arisen with the world. What is the problem?
Both capitalism and communism are bad.
Why?

Because capitalism works and communism doesn't.

And so what is the solution? Something in the middle? We can see that democracy seems to work well, but only when used in conjunction with capitalism. A Communist Democracy is unheard of. And anyway, the will of the many is controlled by the will of a few. Maybe anarchy? No, that wouldn't work either. There is a good reason that anarchists have never won. They are so busy trying to be anarchists that they forget that if they won there would be nothing left to anarchise (is that even a word?). So what are we left with? Fascism, no, it uses capitalist ideals to the extreme. Republicanism. No it also uses capitalism. Socialism? No, it uses communist ideals. Monarchism? No, sorry. That wouldn't work either. Kings and Queens who own alot will ocassionally turn into vile despots. And so we come back to the start. There is no system of rule that is good. All of them are bad. None of them work. So what can we do? Absolutely nothing.

And please, if you find any systems i failed to destroy utterly, please tell me.
